A nano-scale suture structure, observed for the first time, outlines cell membranes and leads to an interlocking interface between lamellae, thus enhancing the bonding and shear resistance.
Although the capacity fades gradually with repeated cycling, a reversible capacity of 300-350 mAh g−1 is maintained for more than 50 cycles, which suggests that the in situ formed Sn--Cu alloy could provide an interlocking interface between active materials and current collector.
The improved properties in (CNT/Al2O3)/PDC are believed to originate from increased surface roughness, which leads to mechanical interlocking at the interface during the pull-out process.
Moreover, the experimental analysis indicated that a combination of worst surface finishing and low viscosity of the molding polymer can result in higher interface interlocking and thus in critical stresses applied to the part during the demolding phase.
There was also evidence of metal debris embedding within the cement mantle originating from the tests of the grit-blasted rods, indicating an extremely strong mechanical interlocking at the interface.
For the plasma treated fibers, scanning electron microscopy shows increased fiber surface roughness due to plasma etching, which favors mechanical interlocking of the interface; X-ray photoelectron spectroscopy analysis indicates increased carbon contents and hydrophobic C C bonds.
Cross sections showed good bonding quality and mechanical interlocking at the bond interface.
Composite slab reinforced with profiled steel decking sheet means there is a provision in the system for positive mechanical interlock between the interface of the concrete and the steel deck by means of embossments.
Trabecular Titanium™ is in fact characterized by an extremely high friction coefficient thanks to its macro-porous structure which fosters the mechanical interlocking at the bone-implant interface.
To provide a high friction surface for physical interlocking at the implant-bone interface and to enhance bone-bonding activity of the titanium implants, porous structures on the surface of the implant have been developed with the use of plasma-sprayed, grid-blasted, fiber-metal or bead-sintered methods.
